LOCK. I

Specification of Letters Patent.

Application filed September 3, 1920. Serial No. 407,846.

T 0 all whom it may concern. I

Be it known that I, SAMUEL SEGAL, a citizen of the United States,'and a residentof New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Locks,

of which'the following is a specification.

Myinvention relates to locks adapted to be fastened to a door or other movable member, the invention relating more particularly to the construction of lock keeper of a character adapted to be fastened to the door frame or other support and to receive the locking bolt of the lock. I

The principal object of the invention is the production of a lock having a novel form of keeper of the character "described which shall be of simple construction and which shall be adjustable both horizontally and vertically to bring it in proper position for reception of the locking bolt in the event that the door or door frame becomes displaced from normal position due to sagging or warping-or through other causes.

A further object of the invention 15 the production of a lock having a keeper which shall automatically make the required horizontal or vertioal adjustment upon contact with the lock casing or a part thereof.

Still other further objects and advantages of the invention will appear from the following description, the invention consisting in the novel parts and combinations of parts hereinafter more particularly described and then specified in the claims.

In the accompanying drawings showing a practical'embodiment'of the invention.

Figure 1 is a plan view of the lock and keeeper as applied to a door and'door frame respectively.

Fig. 2 is a front elevation of thesame.

Fig. 3 is a front elevation of the keeper.

Fig. 4 is a side elevation of the same; Fig. 5 is a horizontal section through the keeper on the line 5-5 of Fig. 3.

Fig. 6 is a front elevation of the slidableplate of the keeper.

Fig. 7 is a front elevation of a modified form of lock and keeper.

Fig. 8 is a front elevation of the modified form of keeper.

Fig. 9 is a side elevation of the same.

Fig. 10 is a horizontal section on the line 101O of Fig. 8. h

Referring in detail to the several figures of thedrawing:

1 indicates a door and 2 a door frame. Fastened to the door, "as by the screws 3 as shown, is a lock casing 4 the end of which is provided with housings 5 preferably integral therewith having transverse slots 6 therebetween. The casing is so mounted on or fastened to the door that the end thereof or the housings 5 extend Over the space between the door and door frame and in front of said frame.

A slidable locking bolt (not shown) is mounted in said casing 4 and is provided with vertical locking hooks or fingers 7 preferably integral therewith which, when in unlocked and raised position, are concealed by the housings 5 and when in locked 7 position extend through the slots 6 as shown in Fig. 1. 8 indicates a conventional tumbler-barrel mounted in the door and having a face plate 9 on the outer face of said door and 10 is an operating knob mounted on the casing 4. The locking bolt is connected to the tumbler-barrel 8 or a part thereof as well as to the operating knob 10 (not shown) so that it may be actuated, as may the hooks or fingers 7 by turning said knob 10 or by inserting and turning a key in the face plate 9. The parts just described are old and well known in the art and accordingly require no detailed or further description.

11 indicates the side wall and 12 the front wall together forming an angle-piece constituting the body of the keeper. Said body is preferably countersunk in the door frame and is connected to the edge thereof by screws 13 passing through the side wall 11. 14 indicates strips preferably'integral with said side wall 11 and parallel thereto and having free forward ends so that they form open channels with said side wall as illus- The plate 15 is friction- Patented Dec. 6, 1921.

said sti-ips through the openings 16' and.

into the front wall 12 and which, by tightening or loosening the same, vary the de-- gree of the clamping engagement of the strips against said platev in an ovious manner.

When the door is in" closed position the perforated ears 17 of the keeper plate enter the slots 6 intermediate'the housings 5 of the lock casing thus bringing them into vertical alinement with the locking hooks or fingers? which are adapted to enter and ex tend through said ears as shown in Fig. 1. If the door or door frame should have become displaced from normal position,'however, so thatthe ears 17 do not enter the slots 6 of the lock casing and the lock in consequence will not function, the position of the keeper plate 15 may be easily adjusted in an obvious manner to obviate the difficulty by merely untightening the screws 18 and then moving the keeper'plate to the proper position desired with the ears in horizontal alinement with the slots 6 where'- upon the screws 18may again be tightened to hold the plate in its adjusted poslti'on.

In most cases I prefer to tighten the screws 18 an amount suflicient merely to prevent the keeper plate from easily sliding or moving out of any given adjusted posi-' tion; Ifthe door or door frame then'beeomes slightly displaced from normal p0- sition the keeper plate will automatically be readjusted to the proper position when the door is closed as the edges or corners of the housings 5-of the lock casing will strike,

against the beveled edges 17 of the perforated ears whereupon the keeper plate will be moved in the proper direction to force the ears in the transverse slots 6. The frictional engagement of the keeper plate with the frontflwall 12 and the strips 14 will be suflicient to holdfit in its adjusted position. i p

In the modification illustrated in Figs. 7 to 10 inclusive, 19 indicates thelock casing fastened to the door by screws 19' and having ahorizontal locking bolt 20 mounted therein which may be actuated by an operating knob 21 or by a key from without the.

door (not shown) as in the preferred form of the invention. The keeper plate15' in this case has substituted for the keeper ears in the preferred form a keeper housing 22 preferably integral with the plate and adapted to receivethelocking bolt 20. Obviously, the keeper plate may be moved or adjusted whenever necessary so that said housing 22 will always be in horizontal I alinement with the locking bolt, 20.
